Traveling Through the Apocalypse Begins with the Creation of Humans

Suddenly traveling through the earth that seemed to be a parallel world, we also landed in America. This world did not have seven continents and five oceans, and all the land was connected into one. Moreover, this world had an outbreak of terrifying unknown viruses, zombies, hybrid beasts, and humanoid monsters. The path forward of mankind completely deviated from the original direction. Fortunately, Zeng Ning has a system called Guardian Core, which can not only create powerful guards of various colors, but also create mechanical equipment for violent killings. He hides in the sheltered castle with iron walls and leaves everything to his guards to sweep everything away. Everything he goes within is his territory, and everyone he sees is his servant. Perhaps conquering the world is his goal.
